sqrt(x^2)-5sqrt(x)+6=0

x^{2} - 5 x + 6 = 0

x = 4, x = 9

Solution steps

x^{2} - 5 x + 6 = 0

Remove square roots

x^{4} - 50 x^{3} + 553 x^{2} + 1800 x + 1296 = 3600 x

Solve

x^{4} - 50 x^{3} + 553 x^{2} + 1800 x + 1296 = 3600 x : x = 1, x = 4, x = 9, x = 36

x = 1, x = 4, x = 9, x = 36

Verify Solutions:

x = 1

False

, x = 4

True

, x = 9

True

, x = 36

False

The solutions are

x = 4, x = 9

2 x + 4 x - 7 = x + 1

- 5 u + 1 + u + 4 = 3

2 = - 3 - x

x + 2 - x - 6 - 2 = 0
